From DualShockers.com (linked above), to quote: "The first is on the disk requirement of the upgrade of select games from the PS3 to the PS4 version. Looks like the PS4′s disk drive will have some work to do.

Jon Haeffele (jj75XP): So for PS3-PS4 game upgrade will the PS3 disc need to be in the PS4 once or will it be every time when trying to play the PS4 version?

Shuhei Yoshida (yosp): every time

The second tidbit of information is on the recently announced support of video capture via HDMI. Don’t expect it for launch, as it will be introduced afterwards with a patch.

Sagman12 (sagman12PC): Will HDMI capture work on day 1 or is it a patch you guys will release after the ps4 launch?

Shuhei Yoshida (yosp): the latter

Finally, some good news. The download speeds from the PSN have never been exactly lightning fast. Looks like things are going to improve with the PS4.

Mike Johnson (Broncosfan1915): Have been trying to download GTAV for the past 4 hours, still not over 30% completed. Hope downloading games is faster on the PS4

Shuhei Yoshida (yosp): It will be.

How will that happen? We don’t know at the moment, but it’s quite probable that Sony will invest in increasing the server count of the PSN with the PS4, especially considering that an increase in PS Plus subscribers is to be expected, given its requirement for online games."

From Engadget (engadget.com/2013/09/19/sony-ps4-hdmi-capture-gesture-control/) via Tokyo Game Show (TGS) 2013, to quote: A couple of features we'd hoped to hear more about have been confirmed, and the first is that the PS4 camera will support both voice and gesture control. It's no surprise that the system will take full advantage of the add-on's dual cameras and four mics for people who want to wave at their TVs, but it's nice to have that confirmed.

Second, in a move that will mostly benefit game reviewers and YouTube video walkthrough experts (thanks for your help on these GTA V missions, all of you), the PlayStation 4 will allow unencrypted HDMI output for games. On the PS3 it didn't, treating games the same as Blu-ray movies, so anyone capturing video in HD needed to use component cables.

That's on top of the console's "Share" button that sends clips of gameplay straight to Ustream, Facebook or PSN. Check out our liveblog for everything else discussed tonight including the PS4's mobile apps, indie gaming and Vita TV.

Update: Sony Worldwide Studios head Shuhei Yoshida tells us via Twitter that HDMI capture on PS4 won't be available at the console's launch this November, but "in the future."

Brad Douglas (kazamatsuri): I think we just announced that we're going to allow video capture of games over HDMI! "Details will follow soon."

Alex Jebailey (CEOJebailey): did they announce gameplay can be captured via hdmi for ps4?

Adam Boyes (amboyes): yep, more details to follow down the road

Shuhei Yoshida (yosp): We announced today that PS4 users will be able to capture their gameplay through HDMI output in the future. We'll update you when ready.

Below is a video on how to start a game with the PlayStation Camera from Shuhei Yoshida, who also states the DualShock 3 is not compatible with PS4 games on PS Vita TV.

It was confirmed at TGS 2013 that PlayStation 4 will work with XBox One's HDMI pass-through port for those curious. The confirmation from Microsoft that the Xbox One will not block the PlayStation 4's video signal comes shortly after Sony revealed that it will not prevent users from capturing video from the PS4's HDMI port.

Shuhei Yoshida talked on what kind of battery life we can expect with the Vita while enjoying remote play, when asked about the processing workload on the Vita, stating the following:

"It’s very inexpensive (in terms of processing workload). Just as much as network communication. I don’t have precise measurements, but the battery life of the PlayStation Vita will be the same as when playing a game online."

He also reassured users that are worried about the number of buttons on the PS Vita, to quote:

"However, compared to the DualShock 4 the number of buttons on the Vita is lower. Conversely the DualShock 4 has no touch screen. The DualShock 4 allows for basic gameplay on the PS4, but in order to allow you to play enjoyably with the PS Vita’s remote play, we’re asking developers to offer custom button mapping for the controller."

Finally, he shared his opinion on the remote play experience, as follows:

"Since the screen is very large, with PS vita games of course, but even when it displays PS3 games via remote play. it looks beautiful. Combine that with PS4 games and it will be amazing. For those that have a PS Vita, the value of the console will increase. If you try it by yourself, I think you’ll realize there’s no better experience."

Interesting. Being able to finally capture gameplay through HDMI will be a major plus that I have been looking forward to on a Sony system. PS Vita TV is a cool thing in my book with an even better price tag too. And I would have been miserable with that digital download of GTA V dragging that bad.

The idea of it not even over 30% complete and its been past 4 hours scares me. I know many may prefer digital over physical games but as long as the option is there, I will ALWAYS prefer a physical copy over a digital one any day.

(And by the way, upon going to the GTA V midnight release to pick up my copy of the collector's edition, it was like going to a block party! lol...)

i just hope the hold on there promise and donot let us wait and down as most future are not available on start they come later with update ..so that make me scare ... as the do the say with psvita and there are realy few game what worth to play on psvita and use what psvita have to offer...
